Locational Privacy

Modern communications mean most individuals today walk around with a beacon that transmits their location. Mobile phones register to a nearby tower as the owner moves through space and the phone company can collect that data in real time or retrospectively to physically place the phone with varying degrees of accuracy. Companies can also determine the owner of every handset within range of a particular tower. GPS enabled phones enable far more precise location placement. Many cars now have GPS devices installed some of which transmit the vehicle’s location to a centralized service. As the devices get cheaper and smaller law enforcement agencies can more easily attach GPS trackers to cars and individuals enabling precise round-the-clock surveillance without ever leaving the precinct. Location-based services including maps of nearby restaurants friend finders and other social networks collect location data as part of providing the service or for contextual advertising.

EFF is fighting to protect the privacy and prevent the misuse of this data that users of phones GPS transmitters and location-based services leak to providers and to the government. In our cell tracking and GPS tracking cases we advocate that the law protect this information by requiring police to get a search warrant before obtaining this sensitive data. We also work to ensure that location based service providers don’t abuse the information they collect on their customers or hand it off to other companies or the police without consent or probable cause.

Mass arrests that sweep up journalists — enabling police and prosecutors to collect electronic evidence they might not otherwise have access to — threatens the independence of the press, said Stephanie Lacambra, a staff attorney at the Electronic Frontier Foundation. The EFF has been working with Jan. 20 arrestees to...

Automated License Plate Readers (ALPRs) may be the most common mass surveillance technology in use by local law enforcement around the country—but they're not always used in the same way.Typically, ALPR systems are comprised of high-speed cameras connected to computers that photograph every license plate that passes. The photo is...

This post is an UPDATE to a piece we originally published last week. Verizon recently rolled out a new pilot project to pre-install on customers’ devices an app launcher/search tool that, we believe, is really just spyware. This software, called AppFlash, is preloaded on a new model...

UPDATE: We have received additional information from Verizon and based on that information we are withdrawing this post while we investigate further. Here is the statement from Kelly Crummey, Director of Corporate Communications of Verizon: "As we said earlier this week, we are testing AppFlash to make app discovery better...
